Part of speech: noun

Definitions

1. Curled, spiral formations within the inner ear that are integral to the auditory system by converting sound vibrations into nervous impulses
2. Fluid-filled, coiled structures found in the inner ear that facilitate hearing by translating sound into electrical signals for the brain
3. Coiled structures inside the ear crucial for detecting sound by transforming vibrations into nerve signals

Etymology: "Cochleas" is simply the plural of "cochlea," the spiral, snail-shaped cavity of the inner ear. Its history goes back to the Ancient Greek "kókhlias," the name for a snail with a spiral shell. The Romans borrowed it as "cochlea," which kept the same meaning, and the word was then taken into English as a technical term for the coiled part of the ear. The shape is the whole story: the inner ear's fluid-filled chamber coils like a shell, and anatomists named it after the snail that carries that same spiral. Because the word is a direct borrowing from Latin, it came into English as a scientific term rather than through everyday speech.

Synonyms: snail shells, inner ear spirals, spiral organs, helical structures
